IMPROVEMENT IN HINGES.

The Schedule referred to vin these Letters Patent .and making part of the sama.

To all whom 'it 'mayconcem Figure 2 is a perspective View ofthe angle or Ipov- I able portion ot' the'hiuge.

Figure 3 isa top view of thehinge.

Figure 4 is a front view ofthe same.

Figure 5 is a vertical central section of the hinge. Similar letters of reference indicate corresponding `parts in the several figures. l

-This invention relates to improvements on that class of hinges for storm-doors, summe1-doors, and gates, which is so constructed that the door or gate to which itisapplied is caused to rise bodily up an inclined plane, while being opened, and to descend,

when in the act of closing, so that the weight of such.

door or gatewill operate to keep it shut, and thus render unnecessary the use of springs or supplemental weights for this purpose.

To enable others skilled in the art to understand my invention, I will describe its construction and op' eration. l

My improvedhinge consists of two principal parts, to wit, a bracket or stationary portion, which is secured rigidly to the frame 4of -the door, at or near the lower end of the door, and an angular portion, which is secured at the lower corner of the door, so as to swing with it. t

'Ihe bracket-portion, shown clearly in figs. 1 and 5, consist of a tlat plate, A, which is perforated, to receive screwsthrough it, a semicircular rail, B, which is cast with the plate A, on one side ot' this plate, and which hasits upper edge c inclined, to receive upon it a small anti-friction roller, h, on theV bottom of -the angle# .iron G.

' At the lowest point inclination of the edgelc, a

` notch, a is formed, which serves as a stop for the said roller h, when the door is shut. v

The semicircular rail B is supported and strengthcned by a rib, d, castwith `this rail, and also with the plate A, which rib also aiiords a support for a lug, b, into which a vertical wrought pin, C, is cast.'

The lug b is cast uponV the front side of the plate A, and upon tbe upper edge of the rib b, and affords a substantial support for the wrought-metal pin G, which latter is arranged in the vertical centre of the semicircular rail B, and receives the-eye g', which is made through the extension g of the angle-iron Gr, as shown in ti 3.

Tlgie angle-portion G of thebinge consists of a stii right-angular Strap or knee, having a'perforated horizontal extension, y, through which thepintle C passes when the door is hung.

One portion of-this angle-iron is secured to the bottorn edge of a door, and the other portion is secured to the vertical edge ofthe door.

.Beneath the horizontal portion ofthe angle-iron G, lugs t 'i are suitably secured, between which is an antifriction roller, h, whichwhen the door is hung, will roll upon the inclined edge c of the bracket-rail B.

It will be seen, from the above description, that I have a right and Yleft hinge, which will cause the weight of the door to close the door, when opened either toward the right or left.

I also attach the door to the bracket or stationary portion, by means of a knee or right-angular strap,

having an anti-friction roller applied beneath it, thereby affording a support for the door, and amuch better` and stronger attachment than is afforded by a simple plate screwed to the vertical edge of the door. The angle-strap or knee serves as a brace, as well as a support, and one limb or arnI' of it strengthens the other.

`It will also be seen that the open rail B is supported from being broken down by the weight of the door, by the rib b; also, that the widest position of this rail'is in a vertical line with the strain which it is required to sustain ;v also, that obstructing objects cannot find lodgement upon its edge.

lt will also be seenthat the piutle C, which is subjected to the strain, andthe shocks and concussione attending the opening and shutting ct a door, is made of wrought-metal, cast into a strong lug, b,on the plate A.

I am aware that hinges, operating upon the general principle of mine, have been long known. and used; but I am not aware th'at a hinge, possessing all the capabilities or advantages of mine,'and constructed as above described, has ever before been known vor used.

Having described my invention,

What I claim as new, and desire to secure by Letters Patent, is i 1. The bracket or stationary portion of the hinge, consisting of the following part-s, to wit, a plate, A, a semicircular rail, B, with inclined edge C, in combination with the ri glut-angled knee-piece G, which is4 constructed with the perforated offset g, and the antifriction roller h, and central notch a; a rib, d,'aln g`, b,

and a wrought-metal pintle C, all arranged. and operating substantially as set forth.

2; The knee or` right angle G, constructed with a perforated oil'set, g, and an autiiiiction roller, k, the said knee being adapted to bear against the lowercorner ofthe gate, door, or shutter, and to extend partly behind the door, shutter, or gate, substantially as and for the purposes described.

i. 3. The combination ot the knee-piece G with an op'en bracket-portion, when both of said parts are1constructed as herein set forth.
